Summary
Flexible nonlinear periodization (FNLP) helps individuals match exercise to resource availability. Decisions aligning with resources supported training, while others served as distractions or social needs, showing varied experiences.
Area of Science:
- Exercise Physiology
- Behavioral Science
Background:
- Flexible nonlinear periodization (FNLP) involves matching exercise demand to individual resource availability.
- Understanding how individuals choose and experience exercise within FNLP is crucial for its practical application.
Purpose of the Study:
- To investigate the viability of FNLP by examining exercise choices and experiences.
- To explore the decision-making processes and outcomes associated with FNLP adherence.
Main Methods:
- Mixed-method study involving 24 participants over 14 days.
- Utilized pre- and postexercise surveys and in-depth interviews.
- Integrated quantitative and qualitative data analyzed via reflexive thematic analysis.
Main Results:
- Resource-concordant exercise decisions positively impacted recovery, training overload, and engagement in novel activities.
- Resource-discordant decisions were linked to stress distraction, social factors, and self-imposed expectations.
- Participant experiences with FNLP were varied, not uniformly positive or negative.
Conclusions:
- FNLP viability is influenced by individual decision-making regarding resource availability.
- Exercise behavior within FNLP is complex, involving factors beyond simple resource matching.
- Findings provide insights for refining FNLP strategies and understanding exercise adherence.
